Description

Technical Field

[0001] The present invention relates to the technical field of power distribution facility detection, and in particular to a transmission line interruption fault detection device. Background Art

[0002] A power outage typically occurs when a transmission line is interrupted due to a fault (such as a line break or equipment failure), preventing the flow of power. This can cause power system instability and potentially lead to power outages or equipment damage.

[0003] After searching, the existing announcement number CN117269847B discloses a power transmission line interruption fault detection device, including a tester fixing plate and two connecting frames. The tester fixing plate is located between the two connecting frames, and a fixing slot is provided inside the tester fixing plate. The device moves around the wire, thereby driving the tester body to move and detect the entire wire section, making it more convenient to use the mobile detection of the entire wire section, so that the device can also perform mobile detection without relying on the wire, which is more convenient for detecting unstable wires and detection in different occasions. It drives the tester body to move outside the local wire, realizing more detection methods and facilitating detection in different locations, eliminating the trouble of moving the tester over a short distance, and making it more convenient to use the tester body for mobile detection.

[0004] Although the above-mentioned transmission line interruption fault detection device can more flexibly detect different positions of the line, it still has the following defects in actual use: (1) It needs to be assembled in a complicated process before detection, which is inconvenient especially when used in the field and high altitude environment; (2) When encountering extreme weather such as wind, sand, rain, snow and strong wind, on the one hand, the tester exposed to the outside is easily directly interfered with, and on the other hand, the rain, snow and particulate matter attached to the surface of the line will cause secondary interference to the test, thereby reducing the accuracy of the detection results. Summary of the Invention

[0005] The object of the present invention is to provide a transmission line interruption fault detection device, aiming to solve the problems existing in the existing transmission line interruption fault detection device.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a transmission line interruption fault detection device, comprising an inductive power measurement module and:

[0007] A triangular shell, wherein a threading area is provided on one side of the triangular shell;

[0008] A drive module disposed within the triangular housing;

[0009] An active winding portion, a transmission portion, and a driven winding portion are symmetrically distributed about the geometric center of the triangular housing, the driving module being capable of being transmission-connected to the active winding portion, and the active winding portion, the transmission portion, and the driven winding portion all comprising a first transmission gear;

[0010] A belt, the two ends of which are respectively wound on the active winding part and the driven winding part, and the belt is in transmission connection with the transmission part;

[0011] The wiring module includes a protective cover, a wiring wheel, a rack, an arc block and a cleaning piece. The wiring wheel is rotatably arranged on the inside of the protective cover, the rack is fixedly arranged on the outside of the protective cover, the first transmission gear is connected to the rack for transmission, the two groups of arc blocks are respectively fixedly arranged at both ends of the protective cover, the cleaning piece is fixedly arranged on the inside of the arc block, the driving module can control the rotation of one group of the wiring wheels, and one group of the protective cover surfaces is fixedly provided with an inductive electrical measuring module.

[0012] As a further solution of the present invention, it also includes an automatic reinforcement structure, which includes a third transmission gear, a reinforcement plate and a second tooth groove. The active winding portion is transmission-connected to the third transmission gear, and the third transmission gear is arranged in a triangular outer shell. A hidden guide rail is provided on the inner side of the threading area, and the reinforcement plate is slidably arranged in the hidden guide rail. A second tooth groove is provided on the surface of the reinforcement plate, and the third transmission gear is transmission-connected to the second tooth groove.

[0013] The beneficial effects of the present invention are as follows: (1) Based on the triangular shell ensuring the stability of the center of gravity, the present invention uses three sets of centrally symmetrical routing wheels to clamp the line. Compared with the traditional single or double sets of parallel routing wheels, it can not only reduce local pressure concentration and reduce the risk of deformation or damage of the line due to uneven force, but also reduce the swing and vibration of the line during the detection process, improve the stability of the detection process and the accuracy of data collection, and more effectively resist external force interference from multiple directions. It can better maintain the stability of the line under adverse weather conditions such as wind and rain, and reduce the impact of external factors on detection.

[0014] (2) The present application utilizes a protective cover to prevent wind, sand, rain, and snow from contacting the tip of the inductive electrical measurement module, and utilizes arc-shaped blocks and cleaning components at both ends of the protective cover to remove rain, snow, particles, and even ice on the line surface, thereby preventing external factors such as particles and moisture from affecting the detection performance of the inductive electrical measurement module, thereby improving the accuracy of the test results and further improving the adaptability of the device to different extreme weather conditions.

The flexible needle clusters are used to remove foreign matter attached to the surface of the line, and the absorbent cotton is used to absorb moisture on the surface of the line, thereby ensuring that the line surface environment detected by the tip of the inductive electrical measuring module 8 inside the protective cover 71 is close to the ideal state, thereby improving the accuracy of the detection data.

[0041] See also Figure 1 and Figure 8 Furthermore, the three intersection positions of the triangular shell 1 are each provided with an accommodating area 13, the driving module 2 is fixedly arranged in one of the accommodating areas 13, and the remaining two accommodating areas 13 are fixedly provided with an integrated battery module 10, which is used to provide power for the driving module 2 and the inductive power measurement module 8.

[0042] See also Figure 1 and Figure 8 Furthermore, a hand grip area 11 is provided on both side sides of the triangular shell 1. The hand grip area 11 is convenient for users to operate on site or at high altitude, and is also convenient for carrying in complex terrain in the wild.

The identification area 15 is an arrow mark, which is used to assist the user in adjusting the position of the triangular shell 1 so that the two groups of integrated battery modules 10 are distributed in parallel below the line. The two groups of integrated battery modules 10 also serve as counterweights and auxiliary balance.

[0043] In an embodiment of the present invention, the inductive electrical testing module 8 is an inductive electrical tester, which uses its tip and internal circuit to monitor whether there is electric field induction and voltage around the circuit to determine internal faults in the circuit. The inductive electrical tester transmits the detection data to the target device via wireless transmission. The inductive electrical tester has a built-in positioning unit. When the inductive electrical testing module 8 detects a circuit fault, the positioning unit automatically outputs the coordinates of the fault location to facilitate the user's subsequent maintenance. The positioning unit can also monitor the position coordinates of the wiring wheel 72 in real time when the wiring wheel 72 clamps the circuit, thereby achieving the purpose of controlling the clamping force of the wiring wheel 72 on the circuit by accurately controlling the displacement of the wiring wheel 72, thereby preventing the insulation layer on the circuit surface from being damaged due to excessive pressure.

[0044] See also Figures 2 to 6 In one embodiment of the present invention, the driving module 2 includes a driving motor 21, a driving shaft 22, a driving gear 23, a first driven gear 26, a first worm 27, a transmission tube 28, a second driven gear 29, an electromagnet 24 and a return spring 25. The driving motor 21 is connected to the driving shaft 22, the driving gear 23 is sleeved on the surface of the driving shaft 22, the first driven gear 26 is fixedly arranged on the surface of the first worm 27, the driving gear 23 can be transmission-connected to the first driven gear 26, the second driven gear 29 is transmission-connected to the transmission tube 28, the driving gear 23 can be transmission-connected to the second driven gear 29, the electromagnet 24 is fixedly arranged on the housing of the driving motor 21, and the return spring 25 is connected between the driving gear 23 and the electromagnet 24.

[0045] See also Figures 2 to 6 Furthermore, the active winding part 3 also includes an active reel 31, a first worm gear 32 and a second transmission gear 34. The first transmission gear 33, the first worm gear 32 and the second transmission gear 34 are all fixedly arranged on the surface of the active reel 31. The first worm 27 is connected to the first worm gear 32, and the third transmission gear 91 is connected to the second transmission gear 34.

[0046] See also Figures 2 to 6 Furthermore, the driven winding portion 5 also includes a driven reel 51, a fixed cover 52 and a coil spring 53. The first transmission gear 33 is fixedly arranged on the surface of the driven reel 51, the fixed cover 52 is fixedly arranged in the triangular shell 1, the driven reel 51 is rotatably arranged in the fixed cover 52, the coil spring 53 is elastically connected between the driven reel 51 and the fixed cover 52, and the two ends of the reel 6 are respectively wound on the surface of the active reel 31 and the driven reel 51.

[0047] See also Figures 2 to 6 Furthermore, the transmission part 4 also includes a gear roller 41, the first transmission gear 33 is fixedly arranged on the surface of the gear roller 41, the surface of the winding belt 6 is provided with a first tooth groove 61, and the gear roller 41 is transmission-connected to the first tooth groove 61.

[0048] See also Figures 4 to 8 Furthermore, the routing module 7 also includes a second worm 73 and a second worm wheel 74. The routing wheel 72 and the second worm wheel 74 are coaxially arranged on the surface of the protective cover 71. The second worm 73 is rotatably arranged on the surface of the protective cover 71. The second worm wheel 74 is transmission-connected to one end of the second worm 73. The other end of the second worm 73 is sleeved in the transmission tube 28. When the driving module 2 controls the active winding part 3 to rotate in the opposite direction, the elastic deformation of the coil spring 53 drives the driven winding part 5 to rotate in the opposite direction. The driven winding part 5 that rotates in the opposite direction controls the transmission part 4 to rotate in the opposite direction through the winding belt 6 and the tooth roller 41, thereby controlling the three groups of routing modules 7 to disengage from the line.

[0049] In an embodiment of the present invention, a magnetic ring is inlaid on the surface of the driving gear 23. When the electromagnet 24 is energized, the electromagnet 24 is magnetically bonded to the magnetic ring. At this time, the driving gear 23 is transmission-connected with the first driven gear 26. The matching structure between the driving shaft 22 and the driving gear 23 is consistent with the matching structure between the second worm 73 and the transmission tube 28. Both are matching structures of sliding connection between the limiting rib and the limiting groove, which are used to realize the functions of coaxial synchronous rotation and relative sliding. When the elastic deformation of the reset spring 25 drives the driving gear 23 to move along the driving shaft 22, the protruding structure at the end of the driving shaft 22 plays a role in axially limiting the driving gear 23, which can ensure that the driving gear 23 moves to a position where it is transmission-connected with the second driven gear 29.

[0050] The structural design of the drive module 2 in this application can allow the user to manually control it by operating the first worm gear 27 and the transmission tube 28 after removing the drive motor 21, drive shaft 22, drive gear 23, electromagnet 24 and return spring 25, which can be suitable for the market positioning of automatic mode and manual mode respectively.

[0051] See also Figure 1 、 Figure 6 and Figure 8 In one embodiment of the present invention, an automatic reinforcement structure 9 is further included, and the automatic reinforcement structure 9 includes a third transmission gear 91, a reinforcement plate 92 and a second tooth groove 93. The second transmission gear 34 is transmission-connected with the third transmission gear 91. The third transmission gear 91 is arranged in the triangular shell 1. A hidden guide rail 14 is provided on the inner side of the threading area 12. The reinforcement plate 92 is slidably arranged in the hidden guide rail 14. A second tooth groove 93 is provided on the surface of the reinforcement plate 92. The third transmission gear 91 is transmission-connected with the second tooth groove 93.

[0052] In an embodiment of the present invention, the rotating active winding portion 3 utilizes the second transmission gear 34, the third transmission gear 91 and the second tooth groove 93 to control the reinforcement plate 92 to connect the two ends of the threading area 12, so as to increase or supplement the strength and stability that are partially missing in the threading area 12, and prevent deformation or breakage when external force acts on the two ends of the threading area 12.

[0053] Working Principle: When in use, first insert the circuit into the triangular housing 1 from the wire threading area 12, then adjust the direction of the triangular housing 1 according to the arrow on the marking area 15 to ensure that the two sets of integrated battery modules 10 are distributed parallel to the circuit. This ensures that the center of gravity of the triangular housing 1 is close to the axis of the circuit, thereby improving the stability of the entire device.

[0054] Then, the driving module 2 is used to control the rotation of the active winding part 3. On the one hand, the rotating active winding part 3 uses the active reel 31 to wind the tape 6. The wound tape 6 not only controls the rotation of the transmission part 4 through the first tooth groove 61 and the tooth roller 41, but also controls the rotation of the driven winding part 5 through the driven reel 51. The active winding part 3, the transmission part 4 and the driven winding part 5 respectively control the routing module 7 to move radially toward the line through the first transmission gear 33 and the rack 75 until the three sets of routing wheels 72 use a certain force to clamp the line. On the other hand, the rotating active winding part 3 uses the second transmission gear 34, the third transmission gear 91 and the second tooth groove 93 to control the reinforcement plate 92 to connect the two ends of the threading area 12 for To increase or supplement the strength and stability that are partially missing in the threading area 12, on the basis of ensuring the stability of the center of gravity of the triangular shell 1, the method of clamping the line by three sets of centrally symmetrical wire wheels 72 can not only reduce local pressure concentration and reduce the risk of deformation or damage of the line due to uneven force, but also reduce the swing and vibration of the line during the detection process, improve the stability of the detection process and the accuracy of data collection, and more effectively resist external force interference from multiple directions (mainly wind interference), and can better maintain the stability of the line under adverse weather conditions such as wind and rain, reducing the impact of external factors on detection;

[0055] During detection, the driving module 2 is used to control the wiring wheel 72 to move along the line. Since the tip of the inductive electrical measuring module 8 is distributed on the inner side of the protective cover 71 and is distributed between the two groups of arc blocks 76 and the cleaning piece 77, the protective cover 71 can prevent wind, sand, rain and snow from contacting the tip of the inductive electrical measuring module 8. The arc blocks 76 made of rigid material and the cleaning piece 77 made of water-absorbing material can remove rain, snow, particulate matter and even ice on the line surface, preventing external factors such as particulate matter and moisture from affecting the detection performance of the inductive electrical measuring module 8, thereby improving the accuracy of the test results and further improving the adaptability of the device to different extreme weather conditions.

[0056] To sum up, based on the triangular shell 1 to ensure the stability of the center of gravity, the present application uses three sets of centrally symmetrical routing wheels 72 to clamp the line. Compared with the traditional single or double sets of parallel routing wheels 72, it can not only reduce local pressure concentration and reduce the risk of deformation or damage of the line due to uneven force, but also reduce the swing and vibration of the line during the detection process, improve the stability of the detection process and the accuracy of data collection, and at the same time more effectively resist external force interference from multiple directions (mainly wind interference), and can better maintain the stability of the line under severe weather conditions such as wind and rain, and reduce the impact of external factors on detection.

[0057] The present application utilizes a protective cover 71 to prevent wind, sand, rain, and snow from contacting the tip of the inductive electrical measurement module 8, and utilizes the arc-shaped blocks 76 and cleaning pieces 77 at both ends of the protective cover 71 to remove rain, snow, particles, and even ice on the line surface, thereby preventing external factors such as particles and moisture from affecting the detection performance of the inductive electrical measurement module 8, thereby improving the accuracy of the test results and further improving the adaptability of the device to different extreme weather conditions.
